With title or figure number to be common or similar, these titles or figure number independently of one another, are not associated between group.
First, the implementation form of the present invention of A groups is belonged to reference to drawing detailed description.
Fig. 1 is that the reverse rotation of threaded body in display A-1 implementation forms prevents from constructing.Such as Fig. 3, the reverse rotation of threaded body
Prevent construction system from possessing male thread body (10), cricoid washer (50), being secured component (80) and base station (90) is formed.
Base station (90) formed to male thread body (10) spiral shell and female spiral hole (92), by base station (90) and male thread body (10) folder
Enter, fixation is secured component (80).
Male thread body (10) is so-called bolt, has head (20) and axle portion (30).In the case where being equivalent to head (20)
The position of portion to root forms screw thread side portions (22).Cylindrical portion (30a) and threaded portion (30b) is formed in axle portion (30).When
So, cylindrical portion (30a) is not necessarily.
The 1st supporting part (60) is formed in a wherein side side for washer (50) (Fig. 1 the upper surface of sides).This 1st supporting part (60)
With screw thread side portions (22) to, therebetween form the 1st snap fastener A.This 1st snap fastener A systems at least threaded body
The direction that side portions (22) are intended to male thread body (10) release to affixed state rotates, then the 1st supporting part (60) and screw thread side
Portions (22) engage with each other, and prevent the relative rotation of the 1st supporting part (60) and screw thread side portions (22) to the direction of rotation.
Opposite side (side below Fig. 1) in washer (50) forms the 2nd supporting part (70).This 2nd supporting part (70) and quilt
Fastening member (80) to.
It is formed being secured component (80) to the component side portions (82) of the 2nd supporting part (70) in washer (50).
It is secured the 2nd snap fastener B of composition between the component side portions (82) of component (80) and the 2nd supporting part (70) of washer (50).
This 2nd snap fastener B at least washers (50) are intended to together with male thread body (10) rotate to release direction, then the 2nd supporting part (70)
It engages with each other, is prevented to the 2nd supporting part (70) of the direction of rotation and the phase of component side portions (82) with component side portions (82)
To rotation.
By the effect of this 1st snap fastener A and the 2nd snap fastener B, male thread body (10) is intended to rotate to release direction,
Then it is clipped in the middle by washer (50), limitation male thread body (10) and the relative rotation for being secured component (80).As a result, prevent public affairs
Threaded body (10) unclamps.
As shown in Fig. 2, in the screw thread side portions (22) of male thread body (10), to form screw thread side concave-convex (24), as the
1 snap fastener A.Screw thread side bumps (24) become continuously sets a plurality of zigzag fashions in the circumferential direction.Screw thread side is recessed
The direction of the direction of convex (24) each extension, i.e. crest line extension becomes the radial direction of male thread body (10).As a result, screw thread side
Concave-convex (24) are extended radially from axle center.
Furthermore this screw thread side portions (22) forms the threaded body taper surface (26) to radial direction inclination.This threaded body
Taper surface (26) because by central side close to flighting front end in a manner of tilt, as a result, as the cone shape of flighting front end side is convex to.
It is more preferably concave-convex (24) on the screw thread side that the formation of this threaded body taper surface (26) had been stated.
As shown in figure 3, the 1st supporting part (60) in washer (50) is formed and screw thread side bumps (24) engage the 1st
Bearing portion side bumps (64), as the 1st snap fastener A.1st supporting part side bumps (64) become continuous in the circumferential direction and set plural number
A zigzag fashion.The direction of the 1st supporting part side bumps (64) each extension, i.e. the direction of crest line extension is along male thread body
(10) radial direction.As a result, the 1st supporting part side bumps (64) are prolonged from the center of the through hole (52) of washer (50) is radial
It stretches.
More preferably the 1st supporting part (60) forms washer side taper surface (66) to radial direction inclination therefore.It bores this washer side
Shape face (66) because by central side close to flighting front end in a manner of tilt due to become mortar shape, as a result, as flighting front end side is concaved towards
Cone shape.It is concave-convex (64) in the 1st supporting part side that the formation of this washer side taper surface (66) had been stated.
As a result, during locking male thread body (10), the threaded body taper surface of the 1st snap fastener A system's screw threads side portions (22)
(26) into the recessed interior of washer side taper surface (66), screw thread side bumps (24) engage with the 1st supporting part side concave-convex (64).The two
Zigzag fashion system such as Fig. 4 (A) shown in, male thread body (10) is intended to rotate to affixed direction Y, then mutual inclined surface 24Y, 64Y
It abuts, the distance one of the two allows opposite slide on one side towards axial separation.On the other hand, male thread body (10) is intended to release
Direction X rotates, then mutual vertical plane (face for tilting larger side) 24X, 64X are abutted, and prevent the relative movement of the two.In particular,
1st snap fastener A more contracts by locking male thread body (10), screw thread side portions (22) and the distance of the 1st supporting part (60)
Short, screw thread side bumps (24) more become strong with engaging for the 1st supporting part side bumps (64), and the engaging for improving release direction X sides is strong
Degree.Herein, the angle of inclination of threaded body taper surface (26) and the angle of inclination of washer side taper surface (66) are different from each other, especially will
The angle of inclination of the off-axis heart of washer side taper surface (66) is set to the angle of inclination of the off-axis heart than threaded body taper surface (26)
It is also narrow and small, therefore the tooth pitch of the unrelated sawtooth for being formed in each taper surface, still can without rocking it lock.
Return to Fig. 3, the outer wall (72) of the 2nd supporting part (70) of washer (50) is the distance of the off-axis heart of screw thread along Zhou Fang
To variation.Particularly, this outer wall (72) is the circle to axle center (center of through hole (52)) bias of screw thread.
On the other hand, the component side portions (82) for being secured component (80) possess the 2nd supporting for accommodating washer (50)
The accommodating recess (84) in portion (70), and the inner wall of this accommodating recess (84) also becomes the circle to the axle center bias of screw thread.In addition,
It is identical with accommodating recess (84) offset in the 2nd supporting part (70), the diameter difference of the 2nd supporting part (70) and accommodating recess (84)
(surplus gap) is set to also smaller than offset.
Therefore, as shown in Figure 1, being accommodated as the 2nd supporting part (70) of washer (50) to the collecting for being secured component (80)
Recess portion (84), then both chimeric as a result, maintaining the state in the axle center of alignment screw thread, the opposite of circumferential direction for limiting the two is revolved
Turn.I.e. this 2nd supporting part (70) is acted on accommodating recess (84) as the 2nd snap fastener B.
More than, the reverse rotation of the threaded body according to A-1 implementation forms prevents from constructing, and is clipped in the middle by washer (50),
The 1st snap fastener A is formed between screw thread side portions (22) and the 1st supporting part (60), in component side portions (82) and the 2nd
The 2nd snap fastener B is formed between bearing portion (70), male thread body (10) is intended to unclamp, then by the engaging machines of the 1st snap fastener A and the 2nd
The restriction effect of structure B both sides becomes the state that male thread body (10) engages with being secured component (80) in the circumferential direction, prevents non-return
Turn to unclamp.Therefore, even if generating vibration still can reach the affixed state that will not be unclamped completely.
Furthermore in this implementation form, screw thread side bumps (24) become in the circumferential direction with the 1st supporting part side concave-convex (64)
Continuous a plurality of zigzag fashion as the 1st snap fastener A, is acted on as so-called ratch mechanism or one-way clutch mechanism.
As a result, allowing the relative movement on screw thread side concave-convex (24) and the 1st supporting part side concave-convex (64) during affixed action, realize smoothly
Relative rotation, on the other hand, release fully limit screw thread side concave-convex (24) and the 1st supporting part side concave-convex (64) when acting
Relative movement.As a result, workability when can allow affixed and release afterwards are prevented reasonably and deposited.
In addition, in this A-1 implementation form, because forming threaded body in screw thread side portions (22) and the 1st supporting part (60)
Taper surface (26), washer side taper surface (66), as the 1st snap fastener A, so the contact area of the two can be increased.It is in addition, public
The affixed power of the axis direction of threaded body (10) is acted on by taper surface also pair radius direction.Mutual taper is towards radius side
It can automatic centering to pushing.As a result, the concentricity of male thread body (10) and washer (50) can be improved, it is recessed to improve screw thread side
The engaging precision of convex (24) and the 1st supporting part side concave-convex (64).In addition, slightly increase inclining for threaded body taper surface (26) of convex side
Oblique angle slightly reduces the inclination angle of the washer side taper surface (66) of concave side, small difference is set also may be used angle.By this method, may be used
It is gradually a little to abut mutual taper surface from center towards radial direction outside with the increase of locking pressure.
In addition, in this A-1 implementation form, avoid the outer wall of the 2nd supporting part (70) of washer (50) and be secured component
(80) shape of the inner wall of accommodating recess (84) becomes concentric circles, as the 2nd snap fastener B to the axle center of screw thread.Change speech
It, the distance of the off-axis heart of the outer wall system screw thread of the inner wall of accommodating recess (84) and the 2nd supporting part (70) changes along the circumferential direction.
By this shape, the inner wall of accommodating recess (84) is chimeric with the 2nd supporting part (70), then keeps being aligned the state in mutual axle center,
Limit the relative rotation of circumferential direction.In particular, herein because of the circular as bias, even if being secured the shape processing of component (80)
It is extremely simple, it is prevented from the relative rotation of the two.
In addition, this A-1 implementation forms system with screw thread side concave-convex (24) with the 1st supporting part side concave-convex (64) for zigzag
Shape, in case of the 1st snap fastener A.But the present invention is not limited thereto.For example, as shown in Fig. 4 (B), can also incite somebody to action
Mutual bumps make chevron into (both sides are inclined surface).By this method, male thread body (10) to unclamp direction X rotation when, that
This inclined surface 24X, 64X relative movement, but along this inclined surface, screw thread side bumps (24) and the 1st supporting part side are concave-convex
(64) separate.This by displacement distance (separated angle [alpha]) be set to it is also big than the lead angle of male thread body (10) if, even if public
Threaded body (10) is intended to unclamp, still because screw thread side concave-convex (24) are more separated with the 1st supporting part side concave-convex (64), so will not be loose
It opens.In addition, this Fig. 4 (B) system is by taking the bumps of section both sides equilateral triangle as an example.But such as Fig. 4 (C), when will unclamp rotation
The inclination angle that the inclination angle of inclined surface 24X, 64X of abutting make inclined surface 24Y, 64Y of abutting during than affixed rotation into is also gentle
Also may be used.By this method, during affixed rotation, because the circumferential direction distance P of inclined surface 24Y, the 64Y that must surmount each other, institute can be shortened
With can reduce it is affixed after rock in (gap).
In addition, as shown in Fig. 4 (D), make the corrugated bumps of peaks and valleys bending, the application as Fig. 4 (A)~4 (C) is also
It can.It can reach when affixed smoothly operational.Furthermore this A-1 implementation forms system by taking the bumps extended to radial direction as an example,
But as shown in Fig. 5 (A), the ditch or mountain (bumps) that form vortex shape (circinate) also may be used.In addition, such as Fig. 5 (B), even if being
The ditch linearly extended or mountain (bumps) remain to be arranged obliquely also in a manner of changing circumferential direction position phase to the radial direction of screw thread
It can.In addition, as shown in Fig. 5 (C), using the circumferential direction of screw thread and the both sides of radial direction it is (planar) formed it is a plurality of subtle
The so-called relief shape of bumps also may be used.
Furthermore it such as this A-1 implementation form, is not necessarily intended to make screw thread side concave-convex (24) and the 1st supporting part side concave-convex
(64) concaveconvex shape is consistent (similar).For example, from the variously-shaped of Fig. 4 and Fig. 5 different shapes is selected also may be used each other.
This A-1 implementation forms system is made into washer side taper surface (66) with making threaded body taper surface (26) into convex
In case of concavity, but the present invention is not limited thereto.For example, such as Fig. 6 (A), threaded body taper surface (26) can be changed
Into flat shape or as Fig. 6 (B) makes concavity into.Washer side taper surface is also the same.Though in addition, without particularly illustrating but for example
If the flexible deformation for effectively applying flexibly washer (50), it is not necessary to which the inclination angle for making both sides' taper surface is consistent.Certainly, only in male thread body
(10) or wherein one square tapered face of washer (50) also may be used.And then the taper surface of both sides can be made into convex or made into recessed
Shape, applying flexibly the flexible deformation of washer touches the two.In addition, for the elasticity of washer to be reached (50), by the base of washer (50)
This shape is set as the so-called spring pad round that helical form is formed and also may be used.
Furthermore as shown in Fig. 7 (A), be set as the 2nd supporting part (70) of washer (50) outer wall and component side portions (82) it
The concentric partial circular arc shape S in axle center of the inner wall of accommodating recess (84) to screw thread, will as the application of A-1 implementation forms
Rest part is set as also may be used as string G cuts into linear shape.I.e. in this situation, the inner wall and the 2nd of accommodating recess (84)
The outer wall of supporting part (70) is also that the distance of the off-axis heart of screw thread changes along the circumferential direction.Therefore, by the shape of string G, accommodate
The inner wall of recess portion (84) engages with the 2nd supporting part (70), limits the relative rotation of circumferential direction.
In addition, as shown in Fig. 7 (B), the outer wall that can be set as the 2nd supporting part (70) of washer (50) is concentric to the axle center of screw thread
Partial circular arc shape S, form the raised T to radial direction extension in rest part.At this point, the inner wall in accommodating recess (84)
It is formed to radius side recess Ao Lying K.By this protrusion T engaging with calixconcavity K, the inner wall of accommodating recess (84) and the 2nd supporting
Portion (70) engages, and limits the relative rotation of circumferential direction.At this point, the calixconcavity K for being formed in accommodating recess (84) is small circular (portion
Cyclotomy arc) preferably.During because of accommodating recess (84) machining, processing that only rodlike drill bit is 1 time, you can formed calixconcavity K it is therefore.
Though in addition, without particularly illustrating but forming calixconcavity (recess) in the 2nd supporting part (70) side of washer 50, in accommodating recess (84)
Side is formed raised also may be used to prominent on the inside of radial direction.
Secondly, the reverse rotation of the threaded body of the A-2 implementation forms of the present invention is illustrated with reference to figure 8 to be prevented from constructing.This inverse rotation
Turn to prevent that construction from being then that male thread body (10) is similary with A-1 implementation forms, but because of washer (50) and be secured component (80)
A construction part it is different, explained with different part, then omitted in relation to male thread body (10) and foregoing common part
Explanation.
Shown in washer (50) system such as Fig. 9 (A), make comparisons with A-1 implementation forms, wall meat is relatively thin, also with being secured structure
Part (80) is convex to the 2nd washer side taper surface (76) in flighting front end direction to being formed to its 2nd supporting part (70) side.
In addition, the outer wall (72) and accommodating recess of 2nd supporting part (70) of washer (50) similary with A-1 implementation forms
(84) inner wall, because as eccentric circular, so being fitted together to each other, limiting the rotation of circumferential direction.
Fig. 8 is returned to, in the bottom surface for the accommodating recess (84) for being secured component (80), forms the component for concaving towards flighting front end side
Side taper surface (86).As a result, being abutted by the 2nd washer side taper surface (76) with washer (50), accepted through washer (50) public
The affixed power of threaded body (10).
And then form pull-up space (88) in an inner wall part for accommodating recess (84).Pull-up space (88) is via collecting
An inner wall part for recess portion (84) is expanded on the outside of radial direction and the depth of increase recess portion is ensured.By this pull-up space
(88), gap is formed in an outer wall part for the 2nd supporting part (70) of washer (50).
Component (80) is secured using male thread body (10) and washer (50) fixation, then the screw thread side of male thread body (10)
Concave-convex (24) engage with the 1st supporting part side concave-convex (64) of washer (50) side, as the 1st snap fastener A.Furthermore washer (50)
The 2nd supporting part (70) outer wall and the inner wall of accommodating recess (84) it is chimeric each other, as the 2nd snap fastener B, limit circumferential direction
Rotation.As a result, preventing the reverse rotation of male thread body (10), i.e., will not unclamp.
Fig. 9 (B) is for the operating instruction for forcing the situation for unclamping male thread body (10).For example, by by yi word pattern spiral shell
In front end insertion pull-up space (88) of silk bottle opener D, by the back side of its front end insertion washer (50).Can in this case, by
By lifting the front end of minus screw bottle opener D, the 2nd supporting part (70) of washer (50) is made to deform upward.As a result, the 2nd supporting
Portion (70) is liberated with the 2nd snap fastener B that accommodating recess (84) is formed, and in this case, makes male thread body (10) to release
If direction rotates, washer (50) can also rotate together, so male thread body (10) can be unclamped.
In addition, this A-2 implementation forms system is in accommodating recess (84) the formation pull-up space for being secured component (80)
(88) in case of, but the present invention is not limited thereto.For example, as shown in Figure 10 (A), due to the outer wall in washer (50)
It is formed inclined surface (77A), the back side for making that the front end of minus screw bottle opener D can be inserted on washer (50) into (is secured component
(80) side).In addition, as shown in Figure 10 (B), the periphery in washer (50) is formed away from being secured the insertion of component (80) with recessed
Portion (77B).This insertion recess portion (77B) be can pass through instead by the back side of the front end insertion washer (50) of minus screw bottle opener D
Side.Other, it is poor using the footpath of the outer diameter and the internal diameter of accommodating recess (84) of washer (50) to be set as, and makes falculate gap, profit
The back side that the front end of minus screw bottle opener D can be inserted into washer (50) with this falculate gap (diagram is omitted) also may be used.
Figure 11 is the anti-locking mechanism of release of the screw thread of display A-3 implementation forms.As shown in Figure 11 (B), male thread body
(10) screw thread side portions (22) become plane shape, and the screw thread side that zigzag fashion is formed at this is concave-convex (24).In addition,
It is formed to keep the narrowing portions (32) of washer (50) in axle portion (30) root of male thread body (10).
Such as Figure 11 (A), the 1st supporting part (60) of washer (50) also becomes flat shape, and zigzag fashion is formed at this
The 1st supporting part side it is concave-convex (64).Through hole (52) in washer (50) forms the engaging protrusion prominent to inner circumferential side (52A),
Engage with the narrowing portion (32) of male thread body (10).It as a result, can be integrated (with reference to) by male thread body (10) and washer (50).
Furthermore in the 2nd supporting part (70) of washer (50), the washer side section portion of the axis direction extension to screw thread is formed
(74).It is then by the pawl for being secured component (80) lateroflexion song herein, forms washer side section portion (74).
On the other hand, there is the structure of the axis direction extension to screw thread in the component side portions (82) for being secured component (80)
Part side section portion (82A).This component side section portion (82A) becomes the drop as being absorbed in flighting front end side.Washer side section portion (74) with
The distance of the off-axis heart of the screw thread in component side section portion (82A) is consistent with each other.Therefore, as shown in Figure 11 (C), male thread body is locked
(10), washer side section portion (74) engages with component side section portion (82A), prevents phase of the washer (50) with being secured component (80)
To rotation.
In addition, this A-3 implementation forms system is with by the narrowing portion of male thread body (10) (32) engaging with washer (50)
Protrusion (52A), in advance by the two integration in case of, but its gimmick is not limited thereto.It for example, also can be at least at it
In a side have magnetism, it is using magnetic force that male thread body (10) is integrated with washer (50).Other, also can be by bonding agent, weldering
It connects, to be pressed into (frictional force) integrated with washer (50) by male thread body (10) in advance.In addition, it is possible to use the auxiliary of O seal etc.
Part is integrated with washer (50) by male thread body (10).
In addition, be herein in case of forming washer side section portion (74) in the periphery of washer (50), it is but of the invention
It is not limited thereto.Such as shown in figure 12, also washer side section portion (protrusion) can be formed in the outer rim inside than washer (50)
(74).The component side section portion that this washer side section portion (74) of collecting is formed in the accommodating recess (84) for being secured component (80) is (recessed
It is hollow) (82A).As a result, washer side section portion (protrusion) (74) engage with component side section portion (calixconcavity) (82A), relative rotation is prevented.
Figure 13 is that the reverse rotation of the threaded body of the A-4 implementation forms of the display present invention prevents from constructing.Such as Figure 13 (A),
The shape of washer (50) is the circle to the axle center bias of screw thread.Washer (50) becomes so-called saucerspring, bears from public affairs
The affixed power of threaded body (10), then to axis direction flexible deformation.
As shown in Figure 13 (B), washer (50) be contained in be formed on the eccentric circular for being secured component (80) collecting it is recessed
Portion (84).The screw thread side portions (22) of male thread body (10) tie up to central side and form screw thread side bumps (24), with washer
(50) the 1st supporting part side concave-convex (64) engaging.In addition, in the outside of the screw thread side of screw thread side portions (22) concave-convex (24)
Form the signature pressure surface (23) directly abutted with being secured component (80).
Furthermore the gap L quilt between the bottom surface of accommodating recess (84) and the screw thread side of male thread body (10) concave-convex (24)
It is set to more slightly smaller than washer (50) axial dimension.As a result, locking male thread body (10), then washer (50) sandwiches accommodating recess (84)
Bottom surface and screw thread side concave-convex (24) and flexible deformation.But this elastic deformation amount have inhibit screw thread side concave-convex (24) with
The degree of the relative rotation of 1st supporting part side bumps (64), that is, enough.The reason is that the affixed power of male thread body (10) is pressed through signature
Face (23) is communicated directly to be secured the event of component (80).Make into that washer (50) itself can be lowered such as this implementation form
Intensity, rigidity, therefore manufacture cost can be reduced.
A-1 is prominent from component (80) is secured with the head (20) of male thread body (10) to A-4 implementation forms system
Exemplified by situation, but if intensification is secured accommodating recess (84) depth of component (80), head (20) can all accommodate receipts
Hold in recess portion (84).
For example, as shown in figure 14, also the 1st supporting part (60) of washer (50) can be made into that male thread body (10) can be accommodated
The cylindrical shape on head (20).The accepting hole on the head (20) for accommodating male thread body (10) is formed in washer (50) the upper surface of
(51).As a result, head (20) are difficult to contact with external member, therefore male thread body (10) is difficult to unclamp.At this point, it can will also become inclined
2nd supporting part (70) of heart circle is defined near head (20) side (upper end side of Figure 14) of washer (50).In this way, it is padding
The both sides that (50) form the peripheral wall (71) of concentric circles and the 2nd supporting part (70) of off-centre operation are enclosed, makes to be fastened on respectively and is secured structure
Part (80), by peripheral wall (71) ensure with the alignment of female spiral hole (92), and both can prevent by the 2nd snap fastener B

Figure 18 is returned to, the outer wall (72) of the 2nd supporting part (70) surrounding of washer (50) is being equivalent to washer side abutting part
(110) part becomes flat shape, and the distance of the off-axis heart of screw thread changes along the circumferential direction.Particularly the 1st washer side abuts
Direction of rotation X of the region (110X) along male thread body (10) wherein side, distance XA, XB, XC become larger.2nd washer side abuts
Region (110Y) turns direction Y along male thread body (10) wherein side's, and distance YA, YB, YC become larger.In addition, except washer side
Part outside abutting part (110) becomes the circular of the distance of the off-axis heart of screw thread centainly.
As shown in Figure 16 (B), it is being secured around the component side portions (82) of component (80), is being formed to male thread body
(10) drop of head side protrusion.This drop is supported to being equivalent to component side to the side wall of the flat shape in washer (50) side
Socket part (120).This component side abutting part (120) is also the distance X variations along the circumferential direction of the off-axis heart of screw thread.Particularly the 1st
Component side abuts the direction of rotation X of region (120Y) along male thread body (10) wherein side, and distance X1, X2, X3 become larger.2nd
Component side abuts the direction of rotation Y of region (120X) along male thread body (10) wherein side, and distance Y1, Y2, Y3 become larger.This
Outside, if if this variation ignores surplus gap slightly, set in washer side abutting part (110) and component side abutting part (120)
Determine into identical.Or this surplus gap by male thread body (10) lock that washer (50) forms that axial compression causes toward axis
The deformation of right angle orientation, the elasticity or deformation that washer (50) is set in a manner of filling up also may be used.
Therefore, the 2nd supporting part (70) of washer (50) is made to be contacted with being secured the component side portions (82) of component (80), then
As washer side abutting part (110) and component side abutting part (120) abut as a result, shape in the axle center for maintaining to be aligned screw thread
State limits the relative rotation of the circumferential direction of the two.I.e. this washer side abutting part (110) and component side abutting part (120) are used as the 2nd
Snap fastener B is acted on.
More than, the reverse rotation of the threaded body according to B-1 implementation forms prevents from constructing, and is clipped in the middle by washer (50),
The 1st snap fastener A is formed between screw thread side portions (22) and the 1st supporting part (60), in component side portions (82) and the 2nd
The 2nd snap fastener is configured around bearing portion (70), male thread body (10) is intended to unclamp, then engages by the 1st snap fastener A and the 2nd
The restriction effect of mechanism B both sides becomes the state that male thread body (10) engages in the circumferential direction with being secured component (80), prevents
Reverse rotation is unclamped.Therefore, even if generating vibration etc. still can reach the affixed state that will not be unclamped completely.
Furthermore in this implementation form, screw thread side bumps (24) become in the circumferential direction with the 1st supporting part side concave-convex (64)
Continuous a plurality of zigzag fashion as the 1st snap fastener A, is acted on as so-called ratch mechanism or one-way clutch mechanism.
As a result, allowing the relative movement on screw thread side concave-convex (24) and the 1st supporting part side concave-convex (64) during affixed action, realize smoothly
Relative rotation, on the other hand, release fully limit screw thread side concave-convex (24) and the 1st supporting part side concave-convex (64) when acting
Relative movement.As a result, the workability and release afterwards when can allow affixed are prevented reasonably and deposited.
In addition, in this B-1 implementation form, because forming threaded body in screw thread side portions (22) and the 1st supporting part (60)
Side taper surface (26), washer side taper surface (66), as the 1st snap fastener A, the contact area that both can increase.In addition, public spiral shell
The affixed power of the axis direction of line body (10) is acted on by taper surface also pair radius direction.Mutual taper is pushed away towards radial direction
Pressure can automatic centering.As a result, the concentricity of male thread body (10) and washer (50) can be improved, it is concave-convex to improve screw thread side
(24) the engaging precision of (64) concave-convex with the 1st supporting part side.In addition, slightly increase inclining for threaded body taper surface (26) of convex side
Tiltedly, slightly reduce the inclination angle of the washer side taper surface (66) of concave side, small difference is set also may be used angle.It by this method, can companion
With the increase of locking pressure, from center towards radial direction outside, mutual taper surface is gradually abutted slightly.
In addition, in this B-1 implementation form, the shape of washer side abutting part (110) and component side abutting part (120) is avoided
Concentric circles is become to the axle center of screw thread, as the 2nd snap fastener B.In other words, washer side abutting part (110) is abutted with component side
The distance of the off-axis heart of the shape system screw thread in portion (120) changes along the circumferential direction.By this shape, washer side abutting part (110)
It is temporarily abutted with component side abutting part (120), then maintains to be directed at mutual axle center, limit the relative rotation of the circumferential direction of bigger.
In particular, since washer side abutting part (110) and component side abutting part (120) are due to not across the all-round shape of male thread body (10)
Both into, the circumferential direction of part is formed in, the formation processing for becoming washer (50) or being secured component (80) is extremely simple, can prevent
Relative rotation, and then can expand open washer (50) or male thread body (10) around.
In addition, this B-1 implementation forms system with screw thread side concave-convex (24) with the 1st supporting part side concave-convex (64) for zigzag
In case of shape is as the 1st snap fastener A, but the present invention is not limited thereto.It, will each other such as shown in Figure 19 (B)
Bumps make chevron (both sides are inclined surface) into and also may be used.By this method, male thread body (10) to unclamp direction X rotation when, that
This inclined surface 24X, 64X is intended to relatively move, but along this inclined surface, screw thread side bumps (24) and the 1st supporting part side are recessed
Convex (64) separate.By this displacement distance (separated angle [alpha]) be set to it is also big than the lead angle of male thread body (10) if, even if
Male thread body (10) unclamps, still because screw thread side concave-convex (24) with the 1st supporting part side bumps (64) are intended to more separate, so will not
It unclamps.In addition, this Figure 19 (B) system is by taking the bumps of section both sides equilateral triangle as an example, but such as herewith Figure 19 (C), will unclamp
Make the inclination angle of inclined surface 24Y, 64Y than being abutted during affixed rotation into the inclination angle of inclined surface 24X, 64X for being abutted during rotation
Also gently also may be used.By this method, during affixed rotation, because can shorten the circumferential direction of inclined surface 24Y, the 64Y that must surmount each other away from
From P, thus can reduce it is affixed after rock in (gap).
In addition, as shown in Figure 19 (D), make the corrugated concave-convex application as Figure 19 (A)~19 (C) of peaks and valleys bending
Also may be used.It can reach smoothly operational when affixed.Furthermore bumps of this B-1 implementation forms system to extend to radial direction
Exemplified by, but as shown in Figure 20 (A), the ditch or mountain (bumps) that form vortex shape (circinate) also may be used.In addition, such as Figure 20 (B),
Even if ditch or mountain (bumps) linearly to extend, the mode for remaining to change compared with the radial direction of screw thread circumferential direction position phase is inclined
Tiltedly configuration also may be used.In addition, as shown in Figure 20 (C), using in the circumferential direction of screw thread and (planar) formation of the both sides of radial direction
The so-called relief shape of a plurality of fine irregularities also may be used.
Furthermore it such as this B-1 implementation form, is not necessarily intended to make screw thread side concave-convex (24) and the 1st supporting part side concave-convex
(64) concaveconvex shape is consistent (similar).For example, from the variously-shaped of Figure 19 and Figure 20 different shapes is selected also may be used each other.
This B-1 implementation forms system is made into washer side taper surface (66) with making threaded body taper surface (26) into convex
In case of concavity, but the present invention is not limited thereto.For example, such as Figure 21 (A), threaded body taper surface (26) can be changed
Into flat shape or as Figure 21 (B) makes concavity into.Washer side taper surface is also the same.Though in addition, without particularly illustrating but example
If effectively applying flexibly the flexible deformation of washer (50), it is not necessary to which the inclination angle for making both sides' taper surface is consistent.Certainly, only in male thread
Wherein one square tapered face of body (10) or washer (50) also may be used.And then the taper surface of both sides can be made into convex or made into
Concavity, applying flexibly the flexible deformation of washer touches the two.In addition, for the elasticity of washer to be reached (50), by washer (50)
Basic configuration is set as helical form and forms so-called cushion round or dish-type spring-like also may be used.
Furthermore as shown in Figure 22 (A), a plurality of places around the 2nd supporting part (70) of washer (50) (are then herein
2 places) formed washer side abutting part (110) also may be used as the application of B-1 implementation forms.At this point, it is formed in component side seat

U2.The special line U1 of a wherein side to radial direction flat shape extend, though the special line U2 of the opposing party to radial direction extend to
Axial displacement.
In addition, be then herein with male thread body (10) to twocouese X, Y rotate when, also inhibit washer (50) rotation structure
Exemplified by making.But the present invention is not limited thereto.At least washer (50) desire is intended to together with male thread body (10) to release direction X rotations
Turn, then the 2nd washer side is kept to abut the abutting state that region (110Y) abuts region (120X) with the 2nd component side, is prevented to this
If the 2nd supporting part (70) of direction of rotation X and the relative rotation of component side portions (82).
As previously discussed, by the effect of the 1st snap fastener A and the 2nd snap fastener B, male thread body (10) is intended to release
Direction X rotates, then being clipped in the middle by washer (50), and limitation male thread body (10) is secured the opposite of component (80) with the 1st
Rotation.As a result, prevent male thread body (10) from unclamping.In addition, also may be used in male thread body (10) to the situation of locking direction Y rotations
Inhibit the rotation together of washer (50) by the 2nd snap fastener B, the snap action of the 1st snap fastener A is made suitably to play.
As shown in figure 28, screw thread side bumps (24) are formed in the screw thread side portions (22) of male thread body (10), as
1st snap fastener A.Screw thread side bumps (24) become sets a plurality of zigzag fashions in the circumferential direction.Screw thread side is concave-convex
(24) direction of the direction of each extension, that is, crest line extension becomes the radial direction of male thread body (10).As a result, screw thread side is recessed
Convex (24) are extended radially from axle center.
Furthermore screw thread side portions (22) form the threaded body taper surface (26) to radial direction inclination.This threaded body is bored
Shape face (26) because by central side close to flighting front end in a manner of tilt, as a result, as the cone shape of flighting front end side is convex to.More
Good is concave-convex (24) on the screw thread side that the formation of this threaded body taper surface (26) had been stated.
As shown in Figure 29 (A), 27 (B), formed in the 1st supporting part (60) of washer (50) and blocked with screw thread side concave-convex (24)
1st supporting part side of conjunction is concave-convex (64), as the 1st snap fastener.1st supporting part side bumps (64) become to be set in the circumferential direction
A plurality of zigzag fashions.The direction of the direction of the 1st supporting part side bumps (64) each extension, that is, crest line extension is along public spiral shell
The radial direction of line body (10).As a result, the 1st supporting part side bumps (64) are radial from through hole (52) center of washer (50)
Extension.
Furthermore preferably the 1st supporting part (60) forms washer side taper surface (66) to radial direction inclination therefore.This washer
Side taper surface (66) because by central side close to flighting front end in a manner of tilt due to become mortar shape, as a result, before screw thread is concaved towards
The cone shape of end.It is concave-convex (64) in the 1st supporting part side that the formation of this washer side taper surface (66) had been stated.
As a result, during locking male thread body (10), the 1st snap fastener A is then the threaded body taper of screw thread side portions (22)
Into the recessed interior of the washer side taper surface (66) of washer (50), screw thread side bumps (24) are concave-convex with the 1st supporting part side in face (26)
(64) engage.Shown in zigzag fashion system such as Figure 30 (A) of the two, male thread body (10) is intended to rotate to affixed direction Y, then mutual
Inclined surface 24Y, 64Y are abutted, and the distance of the two allows opposite slide on one side to axial constriction on one side.On the other hand, male thread body
(10) it is intended to direction X rotations are unclamped, then mutual vertical plane (face for tilting larger side) 24X, 64X are abutted, and prevent the phase of the two
To movement.Especially the 1st snap fastener A is by locking male thread body (10), screw thread side portions (22) and the 1st supporting part (60)
Distance more shorten, engaging for screw thread side bumps (24) and the 1st supporting part side concave-convex (64) more becomes strong, improves release direction X
The engaging intensity of side.Herein, the angle of inclination of the angle of inclination of threaded body taper surface (26) and washer side taper surface (66) is each other
The angle of inclination of the off-axis heart of washer side taper surface (66) is especially set to the off-axis heart of threaded body taper surface (26) by difference
Angle of inclination is also narrow, unrelated can also be formed in the tooth pitch of the sawtooth of each taper surface, locks with will not rocking.In addition, screw thread
The quantity of side bumps (24) and the quantity of the 1st supporting part side concave-convex (64) are not necessarily to unanimously, and then the position phase of circumferential direction
Or position can also make appropriate setting according to the requirement of mechanical strength.
As shown in Figure 29 (D), the shape that the washer lateral incline (110) of washer (50) is blocked with the face at axial right angle is considered
State, then the distance of the off-axis heart of its truncation surface system screw thread along circumferential direction change.Particularly the 2nd washer side abuts region (110Y)
Along the direction of rotation X of male thread body (10) wherein side, distance XA, XB, XC become larger.1st washer side abuts region (110X)
Along the direction of rotation Y of male thread body (10) wherein side, distance YA, YB, YC become larger.It is oblique also to learn that washer rolls from this situation
Face (110) in the circumferential direction can engage component side abutting part (120).
It is explained using Figure 29 (C) from other viewpoint, washer lateral incline (110) is included at least along with male thread body
(10) outside of the radial direction H on the basis of axis, to axial displacement, and along its circumferential direction E also to the small of axial displacement
Inclined surface region V.As a result, as washer lateral incline (110) include with towards the outer diameter direction of male thread body (10) to
Outer advance, the direction position that the 2nd supporting part (70) is proceeded to from the 1st supporting part (60) of the related axial direction towards male thread body (10)
The region of shifting.
In addition, surplus gap slightly or to allow to be intended to and the actively ignorance such as space of flexible deformation of setting
Words, washer lateral incline (110) and component side abutting part (120) are set to identical curved surface.Or with by business threaded body
(10) mode that this surplus gap is filled up in deformation caused by the compression for the axial direction that washer (50) is formed is locked, sets washer
(50) elasticity or shape also may be used.
Therefore, the 2nd supporting part (70) of washer (50) is made to be contacted with being secured the component side portions (82) of component (80), then
As washer lateral incline (110) and component side abutting part (120) abut as a result, maintain to be aligned the state in the axle center of screw thread,
The relative rotation of both limitations circumferential direction S.I.e. this washer lateral incline (110) engages with component side abutting part (120) as the 2nd
Mechanism B is acted on.
More than, the reverse rotation of the threaded body according to C-1 implementation forms prevents from constructing, and is clipped in the middle by washer (50),
The 1st snap fastener A is formed between screw thread side portions (22) and the 1st supporting part (60), in component side portions (82) and the 2nd
2nd snap fastener B is set around bearing portion (70), and male thread body (10) is intended to unclamp, then engages by the 1st snap fastener A and the 2nd
The restriction effect of mechanism B both sides, become male thread body (10) in the circumferential direction the state that engages with being secured component (80) on S, prevent
Non-return rotation is unclamped.Therefore, even if generating vibration etc. still can reach the affixed state that will not be unclamped completely.
And then in this implementation form, screw thread side bumps (24) become in the circumferential direction with the 1st supporting part side concave-convex (64)
Continuous a plurality of zigzag fashion closes mechanism A as the 1st, is acted on as so-called ratch mechanism or one-way clutch mechanism.Knot
Fruit, when affixed action, allow the relative movement on screw thread side concave-convex (24) and the 1st supporting part side concave-convex (64), realize smoothly phase
To rotation, on the other hand, release fully limits the phase on screw thread side concave-convex (24) and the 1st supporting part side concave-convex (64) when acting
To movement.As a result, the workability and release afterwards when can allow affixed are prevented reasonably and deposited.
In addition, in this C-1 implementation form, because forming threaded body in screw thread side portions (22) and the 1st supporting part (60)
Taper surface (26), washer side taper surface (66), as the 1st snap fastener A, so the contact area of the two can be increased.It is in addition, public
The affixed power of the axis direction of threaded body (10) is acted on by taper surface also pair radius direction.Mutual taper is towards radius side
It can automatic centering to pushing.As a result, the concentricity of male thread body (10) and washer (50) can be improved, it is recessed to improve screw thread side
The engaging precision of convex (24) and the 1st supporting part side concave-convex (64).In addition, slightly increase inclining for convex side limb threaded body taper surface (26)
Tiltedly, slightly reduce the inclination angle of the washer side taper surface (66) of concave side, small difference is set also may be used angle.It by this method, can companion
With the increase of locking pressure, from center towards radial direction outside, mutual taper surface is gradually slightly abutted.
In addition, in this C-1 implementation form, including washer side abutting part (110) opposite to one another and component side abutting part
(120) circumferential direction X, Y position of the shape (hatching G) of the axis orthogonal cross-section of the online appropriate location of axis along male thread body (10)
The region of shifting, as the 2nd snap fastener B.By this shape, washer lateral incline (110) is temporary with component side abutting part (120)
It abuts, then limits the relative rotation of the circumferential direction of bigger, while the axle power of threaded body is by washer lateral incline opposite to one another
(110) conveyed with component side abutting part (120).I.e. because the restraint for being made relative rotation using the axle power of threaded body is acted on, so
More locking screw body more can prevent relative rotation really.However, even if convey the locking of degree strong hardly to generate axle power
Degree, screw thread side bumps (24) and the 1st supporting part side concave-convex (64) still it is abundant it is chimeric if, the rotation of specific direction can be substantially prevented from
Turn i.e. rotation to unclamp.
In addition, washer side abutting part (110) can be made into curved surface, by mutual flexible deformation, with component side abutting part
(120) touch.As a result, when threaded body is affixed, so-called rock can inhibit.Especially as this implementation form, the 1st is secured component
(80) for cylinder or cylindrical shape component situation, can effectively apply flexibly the shape of this circumferential surface, make washer lateral incline (110) with
Component side abutting part (120) touches.
In addition, this C-1 implementation forms system with screw thread side concave-convex (24) with the 1st supporting part side concave-convex (64) for zigzag
In case of shape is as the 1st snap fastener A, but the present invention is not limited thereto.For example, as shown in Figure 30 (B), can also incite somebody to action
Mutual bumps make chevron into (both sides are inclined surface).By this method, male thread body (10) to unclamp direction X rotation when, that
This inclined surface 24X, 64X relative movement, but along this inclined surface, screw thread side bumps (24) and the 1st supporting part side are concave-convex
(64) separate.By this displacement distance (separated angle [alpha]) be set to it is also big than the lead angle of male thread body (10) if, even if public
Threaded body (10) is intended to unclamp, still because screw thread side concave-convex (24) are more separated with the 1st supporting part side concave-convex (64), so will not be loose
It opens.In addition, this Figure 30 (B) system is by taking the bumps of section both sides equilateral triangle as an example.But as shown in Figure 30 (C), revolved unclamping
The inclination angle of inclined surface 24X, 64X of abutting make the inclination angle of inclined surface 24Y, 64Y of abutting during than affixed rotation into also when turning
Gently also may be used.By this method, during affixed rotation, because the circumferential direction distance of inclined surface 24Y, the 64Y that must surmount each other can be shortened
P, thus can reduce it is affixed after rock in (gap).
In addition, as shown in Figure 30 (D), the corrugated bumps for making peaks and valleys bending can be also set, as Figure 30 (A)~30
(C) application.It is smoothly operational when can reach affixed.Furthermore this C-1 implementation forms system is recessed to extend to radial direction
Exemplified by convex, but as shown in Figure 31 (A), the ditch or mountain (bumps) that form vortex shape (circinate) also may be used.In addition, such as Figure 31
(B), even if ditch or mountain (bumps) linearly to extend, remain in a manner of changing circumferential direction position phase to the radial direction of screw thread
It is arranged obliquely and also may be used.In addition, as shown in Figure 31 (C), using in the circumferential direction of screw thread and both sides (planar) shape of radial direction
The so-called relief shape of fine irregularities of pluralizing also may be used.
Furthermore it such as this C-1 implementation form, is not necessarily intended to make screw thread side concave-convex (24) and the 1st supporting part side concave-convex
(64) concaveconvex shape is consistent (slightly similar or slightly congruent).For example, from Figure 30 and Figure 31 it is variously-shaped select each other it is different
Shape also may be used.
This C-1 implementation forms system is made into washer side taper surface (66) with making threaded body taper surface (26) into convex
In case of concavity, but the present invention is not limited thereto.For example, as shown in Figure 32 (A), it can be by threaded body taper surface (26)
And washer side taper surface (66) makes flat shape into.It is used in addition, for example being formed in the root of the axle portion (30) of male thread body (10)
The narrowing portion of washer (50) (32) to be kept also may be used.It is prominent that through hole (52) in washer (50) forms the engaging prominent to inner circumferential side
It rises (52A), engages with the narrowing portion (32) of male thread body (10).It can be in advance by male thread body (10) and washer as a result, becoming
(50) it is integrated (with reference to).
In addition, such as the male thread body (10) of Figure 32 (B), threaded body taper surface (26) is concaved towards to the shape on screw thread side instead
Shape also may be used.Though in addition, if flexible deformation without particularly illustrating but for example effectively applying flexibly washer (50), it is not necessary to bore both sides
The inclination angle in shape face is consistent.Certainly, only also may be used in wherein one square tapered face of male thread body (10) or washer (50).And then
It can make the taper surface of both sides into convex or make concavity into, applying flexibly the flexible deformation of washer touches the two.In addition, in order to reach
To the elasticity of washer (50), the basic configuration of washer (50) is set as so-called spring pad round or the plate-like that shape of threads is formed
Spring-like also may be used.
Figure 33 is that the reverse rotation of the threaded body of display C-2 implementation forms prevents from constructing.As shown in Figure 33 (A), male thread
The screw thread side portions (22) of body (10) become flat shape, and the screw thread side that zigzag fashion is formed at this is concave-convex (24).Pad
Enclosing the 1st supporting part (60) of (50) also becomes flat shape, and the 1st supporting part side that zigzag fashion is formed at this is concave-convex (64).
And then as shown in the bottom view of Figure 33 (C), the 2nd supporting part (70) of washer (50) is along male thread body (10)
Axial, center becomes convex.Particularly become to the section shape of axis right angle orientation and the ellipse hemisphere of approximate ellipse, at it
It is centrally formed through hole (52).Using this shape, washer lateral incline (110) is formed in the whole district of the 2nd supporting part (70).Including
In this washer lateral incline (110), the axis orthogonal cross-section of the online appropriate location of axis of male thread body (10) or through hole (52)
Shape (hatching G), along circumferential direction X, Y of male thread body (10), the region of displacement on the basis of axle center.Particularly, become
Washer lateral incline (110) includes advancing inwardly with the radial direction towards male thread body (10), related towards male thread body
(10) region of the direction displacement that the 2nd supporting part (70) side is proceeded to from the 1st supporting part (60) of axial direction.I.e. this washer rolls
Inclined-plane (110) is with towards the inside of radial direction H, washer lateral incline (110) is convex to the 1st mode for being secured component (80) side
It tilts.In addition, along elliptical short axle and long axis, extend special line or special line U.
On the other hand, as shown in Figure 33 (B) the upper surface of figure, the 1st be secured the component side portions (82) of component (80) also into
For such as oval hemispheroidal concavity, female spiral hole (92) is centrally formed in its bottom surface.Utilize this component side portions (82)
Shape forms component side abutting part (120).The online appropriate location of axis of component side abutting part (120) including male thread body (10) it
Region of the shape (hatching G) of axis orthogonal cross-section along circumferential direction X, Y displacement on the basis of axle center of male thread body (10).Cause
This, if locking male thread body (10), washer lateral incline (110) is abutted with component side abutting part (120), can convey male thread
The axle power of body (10), while washer (50) and the 1st is prevented to be secured the relative rotation of component (80).
In this way, the situation of the component side portions (82) in a part of calixconcavity as made tubing, it can be by the 2nd of washer (50) the
Supporting part (70) is convex to the bowl-type of the 1st non-circular for being secured component (80) side instead, touches the two.In particular, as by
Can the axle power of male thread body (10) be effectively communicated to the 1st by the face contact area of mortar shape and be secured component (80).
Figure 34 is that the reverse rotation of the threaded body of display C-3 implementation forms prevents from constructing.As shown in Figure 34 (A), male thread
The screw thread side portions (22) of body (10) become flat shape, and the screw thread side that zigzag fashion is formed at this is concave-convex (24).Pad
Enclosing the 1st supporting part (60) of (50) also becomes flat shape, and the 1st supporting part side that zigzag fashion is formed at this is concave-convex (64).
And then the 2nd supporting part (70) of washer (50) becomes the axially inclined single plane to male thread body (10).Profit
With this shape, washer lateral incline (110) is formed in the 2nd supporting part (70).This washer lateral incline (110) system and male thread body
(10) distance of the axis section shape (hatching G) at a right angle along the off-axis heart of circumferential direction displacement of male thread body (10).
On the other hand, the 1st component side portions (82) for being secured component (80) also become the axial direction to male thread body (10)
The single plane of inclination.Using the shape of this component side portions (82), the section at a right angle with the axis of male thread body (10) is formed
Shape is along the component side abutting part (120) of the distance of the off-axis heart of circumferential direction displacement of male thread body (10).Therefore, public spiral shell is locked
If line body (10), washer lateral incline (110) is abutted with component side abutting part (120), conveys the axle power of male thread body (10),
Simultaneously washer (50) and the 1st is prevented to be secured the relative rotation of component (80).
In this way, the 2nd of washer (50) can be formed in component side portions (82) as the situation to axially inclined plane
